CTICasesCystic Sarcoidosis in HIV
Imaging findings
Chest radiograph and CT of a patient with well-controlled HIV show multiple small perilobular nodules along the bronchovascular bundles and fissures, along with atypical, confluent cystic spaces in the middle lobe and lingula.
Key takeaways
Sarcoidosis can rarely present with atypical cystic or bubbly lung changes, which typically track along the bronchovascular bundles. This must be distinguished from lymphocytic interstitial pneumonitis (LIP) or other HIV-associated lung diseases.
